BOTTLE-WASHING BRUSH.

SPECIFICATION forming part of Letters Patent N0. 778,931, dated January 3, 1905.

Application filed August 27, 1903. Serial No. 170,900.

To all whom t may concern:

Be it known that I, ADoLrH R. VVIENs, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Bottle-Washing Brushes; and I do hereby declare that the following' is a full, clear, and exact description thereof.

My invention has for its object to provide simple economical brushes for bottle-washing machines, as well as to enhance the durability of such brushes and to render the same more effective in operation than those ordinarily employed.

Hence said invention consists in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed. 1

Figure 1 of the drawings represents a sectional view of a brush made in accordance with my invention for attachment to a waterconduit in a bottle-washing machine to be inserted through the mouth of the bottle and spread therein, so as to have frictional contact with the bottom and wall of same; Fig. 2, a horizontal section of the brush on the plane indicated by line 2 2 in the first figure,

and Figs. 3 and 4 elevations of parts of said brush.

Referring by letter to the drawings, A indicates a sleeve the bore of which is contracted approximately midway of its length, and back of this bore contraction the sleeve is tapped to be coupled to a screw-threaded end of a water -conduit in a bottle washing machine, the water from the conduit having escape through a port provided in said sleeve. The contracted portion of the sleeve-bore is also tapped, and engaging the rsame is a screwthreaded and shouldered stem B, herein shown as being extended through an opening in a socket C, but which-may be integral with the socket to constitute a shank of same if found more convenient in practice.

Bound and cemented or otherwise held on the stem B is pliable brush material D, preferably bristles or other fibrous substance, the same being clamped at one end in the sleeve A when said stem is engaged with the contracted bore of said sleeve.

Held in the socket C by the stem B, as herein shown, or by other suitable means is the butt of a tuft of pliable brush material E, preferably bristles or other fibrous substance, and the preferably conical inner end of said socket serves as a spreader for the brush material D, that is further spread as a result of centrifugal force to have good frictional contact with the interior of the wall of a bottle within which the brush is rotated, the interior of the bottom of said bottle and the brush material E being at the same time in like contact.

In practice there is compression of the pliable brush material D E to permit of the brush entering a bottle; but because of the disposition of said material there is no crushing strain thereon incidental to its compression. Hence the durability of the brush is enhanced, and owing to the tendency of some of the aforesaid material to spread under centrifugal force the brush as a whole has been found more effective than those ordinarily employed in bottle-washing machines.

Having thusdescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-- y 1. The combination of a sleeve attachable to a water-conduit of a bottle-washing machine and provided with an outlet, a stem having screw-thread connection with the sleeve, brush fiber-held in connection with the stem in the sleeve, and a spreader for the brush material in conjunction with said stem.

2. The combination of a sleeve attachable to a water-conduit of a bottlewashing machine and provided with an outlet, a stem having screw-thread connection with the sleeve, brush ber held in connection with the stem in the sleeve, a socket on said stem to constitute a spreader for the brush material, and brush liber held in the socket.

3. The combination of a sleeve attachable to a water-conduit of a bottle-washing machine and provided with an outlet, the bore of In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in IO the county of Milwaukee and State of Wisconsin, in the presence of two Witnesses.
